更改章节标题样式

Question

我需要更改在该网站的另一个页面上找到的以下代码，以便\chapter{Intro}在左侧的水平线上方显示章节标题（例如）：

\documentclass{report}
\usepackage{lmodern}
\usepackage{titlesec}
\usepackage{microtype}
\usepackage{tikz}

\definecolor{myblue}{RGB}{0,82,155}
    \titleformat{\chapter}[display]
  {\normalfont\bfseries\color{myblue}}
  {\filleft%
    \begin{tikzpicture}
    \node[
      outer sep=0pt,
      text width=2.5cm,
      minimum height=3cm,
      fill=myblue,
      font=\color{white}\fontsize{80}{90}\selectfont,
      align=center
      ] (num) {\thechapter};
    \node[
      rotate=90,
      anchor=south,
      font=\color{black}\Large\normalfont
      ] at ([xshift=-5pt]num.west) {\textls[180]{\textsc{\chaptertitlename}}};
    \node[
      font=\color{white}\Large\normalfont,
      anchor=north,
      inner sep=0pt
      ] at ([yshift=2.5cm]num.north) {\chaptertitlename};
    \end{tikzpicture}%
  }
  {10pt}
  {\titlerule[2.5pt]\vskip3pt\titlerule\vskip4pt\LARGE\rmfamily}

\begin{document}

\chapter{Introduction}

更新

titlesec您可以尝试使用以下代码的明确选项：

\documentclass{report}
\usepackage{lmodern}
\usepackage[explicit]{titlesec}% use option explicit
\usepackage{microtype}
\usepackage{tikz}

\definecolor{myblue}{RGB}{0,82,155}
\titleformat{\chapter}[display]
{\normalfont\bfseries\color{myblue} }
{%
\parbox[b]{\dimexpr \textwidth-4cm}{\LARGE\rmfamily\raggedright#1}\hfill % use a parbox for longer titles   
    \begin{tikzpicture}
        \node[
        outer sep=0pt,
        text width=3cm,
        minimum height=3cm,% expanded to accommodate two digits
        fill=myblue,
        font=\color{white}\fontsize{80}{90}\selectfont,
        align=center
        ] (num) {\thechapter};
        \node[
        rotate=90,
        anchor=south,
        font=\color{black}\Large\normalfont
        ] at ([xshift=-5pt]num.west) {\textls[180]{\textsc{\chaptertitlename}}};
    \end{tikzpicture}%
}
{4pt}
{\titlerule[2.5pt]\vskip3pt\titlerule}

\begin{document}
    \setcounter{chapter}{9} % test two digits
    \chapter{This is a bigger chapter title that needs to be adjusted here}
\end{document}
